Neither company disclosed financial terms of the deal, but the plan is for Caviar and Zesty to operate independently in the short term.

“Restaurants turn to Caviar to reach more diners and grow their businesses,” Square Caviar Lead Gokul Rajaram said in a press release. “Expanding our corporate catering product with Zesty enables us to offer our restaurant partners another way to boost sales through higher-margin, large-format catering orders,” said Rajaram, Caviar Lead at Square. “Caviar is thriving, and we’re excited to supercharge its success with Zesty and double down on an area with great opportunity to drive more growth for our business.”

Since its acquisition of Caviar in 2014, Square has acquired OrderAhead’s pickup business to launch Caviar Pickup and Entrees On-Trays to expand its footprint in the Dallas-Fort Worth, Texas area.

Zesty currently partners with about 150 restaurants in San Francisco, which is the only city in which it operates. Some of Zesty’s customers include Snap, Splunk and TechCrunch. Zesty, which first launched in 2013 under a different name, had previously raised $20.7 million in venture funding.

“Adding Zesty’s offerings, like sophisticated menu-planning tools and algorithms, white-glove catering services, and nutrition and allergen customization, will help us expand our catering offering and even better serve companies of all sizes,” the Caviar team wrote on Medium. “Plus, it provides our restaurant partners with more opportunities to reach new corporate customers.”
